11907 USB exception ?due to low speed port blueytoo "Win7-64bit guest. MacOS 10.6.8 64bit host.
USB Oscilloscope Siglent SDS 1102CML using NI-VISA USBTMC driver 5.1.2, EasyScopeX software.
This particular software seems a bit underbaked and not well documented. It does actually work in Bootcamp having been advised exactly which driver version to install. Has take a few days to get this far!
In VB, it does not work. There are 2 issues:
1. Despite USB2 support being checked, the device attaches to a low speed port, and Windows report this as a problem.
2. Trying to connect to the oscilloscope generates a timeout exception.
Logs attached.
